Airborne LiDAR: this monitoring instrument is able to acquire 3D point clouds used to generate digital surface (DSM) and digital terrain models (DTM). GMG has in charge a IGI Litemapper 6800, coupled to a digital camera for photogrammetric acquisitions The system is mounted on a pod certified to fly on helicoptersEUROCOPTER AS 350.

Terrestrial LiDAR: this system is used to acquire 3d point clouds used to generate digital elevation models. The Lase is coupled to a semimetric digital camera to generate textured digital models. This kind of data is particularly useful for the analysis of sub-vertical rock walls. GMG owns a Riegel LMS- Z420i.

GPS: this instrument is essential in several monitoring scenarios, either to to set up geodetic networks, or to geocode data acquired with other monitoring approaches. GMG owns seven Leica receivers as well as a permanent GNSS Topcon station installed in-house.

Single beam – side scan sonar: To supply a particular typology of surveys, GMG has build this monitoring system, which is used mainly to perform bathymetric acquisitions and obtain acoustic images of river beds. This instrument is very important to evaluate river bed erosion and/or sediment accumulation.

Inclinometric probe: this system is essential to monitor the evolution of deep seated deformation of a landslide phenomenon. In general, the probe is used manually to measure the deformation of inclinometric pipes inserted within boreholes realized ad-hoc on and around the landslide body. The GMG owns OTR and Slope Indicator inclinometric probes. The same probe might be utilized whitin the Automated Inclinometric System patented by GMG.

Robotized Total Station (RTS): this monitoring instrument is very effective in several operative scenarios. RTS are moder theodolites able to automatically measure the position of artificail targets (optical prisms) installed in the area of interest with sub-centimetric accuracies. GMG owns and runs several RTS models build and distributed by the leader companies Leica and Topcon.

GMG Mobile Lab: is a equipped to contain all necessary instruments to be used mainly in emergency contexts. The Mobile laboratory has been projected in order to be dynamically configured depending on the specific use and/or particular geohazard scenario.
